The rapid growth of the World Wide Web has created new industries and exten
ded the reach of existing businesses. One of the areas on the verge of expa
nsion is electronic commerce (EC). While still in its infancy, EC is foreca
sted to increase by over an order of magnitude over the next several years.
Notable success stories of selling over the Web-such as those of amazon.co
m and Dell Computer-are often touted today. A major concern with the creati
on of EC systems today is the large amount of customization and systems int
egration work required. We present here the MediaXact(TM) system, a solutio
n to this dilemma that provides a framework separating the service presenta
tion and service logic from the functions that make up the service. This gr
eatly simplifies customization and eases the integration with existing lega
cy systems and business logic.
